Chelsea are currently in poor condition, their performance in pre-season is very disappointing, there is no significant development shown under the current coach, poor defense is one of Chelsea's weaknesses, last season and this season only show disappointment for the fans, there needs to be a real overhaul that can rebuild Chelsea's glory, yes and it seems there is no hope for Chelsea in the competitive league which is now getting closer
You don't need to take preseason games seriously and there is no reason to say what you said. It is too early to say that Chelsea performance is bad and has no hope of returning to its glory days while the season has not started.
What you need to know now to avoid worrying is to consider pre season match as games to test young players or give all players a little chance to show their own style of play without taking this match seriously. And we haven't seen Enzo real contribution yet, but we need to see at least Chelsea first 10 games and if they get good results from the 10 match, Chelsea still has a chance.
